Had to walk back and forth between concourses to figure out which gate I was supposed to be at. The app and the flight board in the airport had different gates listed. Was told numerous times to check bags only to get on the plane and find that there was plenty of room for bags. The flight was over an hour late which had me landing after the last train departed. WiFi was unusable

My experience was okay I changed my returning flight and I was charged extra money which I dont think should be the case, especially because I experienced small delays from my going flight. And many flights were either canceled or delayed after my original flight time. I believe some customers should have the ability to change flights due to certain situations

WiFi was inoperable - second in four recent Southwest flights where that was true. I need WiFi for work and if Southwest cannot provide, I’ll stop using it

Your computers were down and took a long time to check baggage

Flight attendant skipped about 6 rows for drink service. I got a side eye when I asked for a drink - like it was an inconvenience or my mistake. He shouldn't be on a flight if he doesn't like his job and doesn't have customer service first attitude.

They did not fix the wifi that they knew was an issue on an earlier flight. The flight was filled with business people that were clearly frustrated not being able to work. That can’t happen on a 3 1/2 hour flight. Would rather have been delayed a bit.

Eveeyrime I fly they are begging for bags due to cabin overhead space. What they should so ia take the bags that are clearly too big to fit wheels first on their side. And those of us who give up the bag should really get their bags first. When boarding, nobody wants stupid jokes about how hot it is on board. Give us some cool air. Im usually sick from the heat by the time we take off.

My experience will Southwest was good. I wish there was more entertainment and the boarding process was slow at time but other than that my experience was great definitely will be flying with SouthWest again.

if I was good. Not happy that I have to pay extra money to get the seat I need for lake room, but I guess that’s a sign of the times.

Great flight. Good snacks and drinks. Grateful it was free. The flight from Nashville to louisville, i think her name was Tracy (not sure that's right) super awesome, nice and cheerful. She really enjoyed being at work today! She was the person who scanned the boarding pass on flight wn941. She should be recommended for a raise !

I didn't like anything about this flight. The only reason anyone drinks Jack is because you ran out of Woodford. You should know to stock more Woodford. When you wait of first class hand and foot from the minute they get on the plane 5 feet from me but then start service from the rear of the plane so main cabin plus gets the scraps, that's how you get people to stop flying your airline.

The flight was normal, until it wasn't. I fell asleep after boarding, woke up still on the ground, the flight couldn't leave the gate due to mechanical issues, including a/c failure. The air felt thin, similar to high altitudes, not sure if that's why I fell asleep but it happened to the passenger next to me too. They hooked us up to external air but it didn't seem to help much. They finally decided to deboard us after nearly 2 1/2 hours. We reboarded about 45 minutes later and landed about 3 hours 15 minutes late. Some passengers got water or something but I was never offered either. Honestly, with that big of a delay, they should have provided full service to make sure their sweating passengers had fluids. Yes, it was a typical over 90 degree day in Texas. The lady in front of me said she was getting a heat rash. It was rough . . .

Flight was delayed and so much of inconvenience related to the gate change.

Flight was smooth and on time: however, this flight was filled with advertising. We got it over the speaker system both when we took off and when we landed. Flight attendants were handing out sales flyers when we landed. It was not a good look.

The flight was delayed almost three hours. I understand delays happen from time to time, but this flight was delayed no less than 10 times. I wish the amount of time of the delay was more accurate, versus delaying in 10 or 20 minute increments many, many times.

Delayed by 5 hours and I had to wit in the airport for more than 6+ hours.

technology worked well and everything ran smoothly. The seats are quite cramped so please don't try to re-engineer the cabin to squeeze more bodies on board.

Flying in the United States with the major airlines has become so underwhelming. A 2-3hr flight in most other parts of the world with the major carriers of the area comes with newer, CLEANER aircraft and significantly better in flight service in terms of both staff attitude and a actual meal service.

The pilot greased the landing and the crew was fantastic.

Crew should be nicer and emphatic with customers. Same cookies as the past 20 years. Seat are ok and the plane was clean though it was delayed.
